might pull in libpthread. This is quite bad, firstly because it can
cause oplock signals on Linux to go wonky, and secondly because merely
linking with pthreads can cause performance degradations due to implicit
locking requirements.
The solution is to only search for clock_gettime if --with-profiling-data
was specified. If we do end up searching for it, then we test whether
linking with librt pulled in libpthread, and we only allow the definition
for clock_gettime to succeed if libpthread was NOT linked in.
Problem reported by Thomas Bork and diagnosed by Volker Lendecke.
Fix more potential segfaults when something on our way to a DC connection
fails.
We can not continue if dcip_to_name() fails. With
192.168.234.100 nt4pdc
192.168.234.100 windows#1c
192.168.234.100 windows#1b
in the lmhosts file when nt4pdc is rebooted, we do find the DC's IP address,
we can connect to TCP 139 while it is booting but anything else fails. So we
fall back to put the IP address into domain->dcname. When the DC is fully up
later on we try to do the auth2 against \\192.168.234.100 which gives
INVALID_COMPUTER_NAME. And we never get out of this loop again.
Fix this.
Jerry, maybe you can take a look.
Thanks,
Volker
more scalable:
The most efficient way is to use the "tokenGroups" attribute which gives
the nested group membership. As this attribute can not always be
retrieved when binding with the machine account (the only garanteed way
to get the tokenGroups I could find is when the machine account is a
member of the "Pre Win2k Access" builtin group).
Our current fallback when "tokenGroups" failed is looking for all groups
where the userdn was in the "member" attribute. This behaves not very
well in very large AD domains.
The patch first tries the "memberOf" attribute on the user's dn in that
case and directly retrieves the group's sids by using the LDAP Extended
DN control from the user's object.
The way to pass down the control to the ldap search call is rather
painfull and probably will be rearranged later on.
Successfully tested on win2k sp0, win2k sp4, wink3 sp1 and win2k3 r2.

Expand the "winbind nss info" to also take "rfc2307" to support the
plain posix attributes LDAP schema from win2k3-r2.
This work is based on patches from Howard Wilkinson and Bob Gautier
(and closes bug #3345).

to make connections to ports 445 or 139 on the DC it's trying
to contact. It calls sys_select() on the non-blocking sockets,
not sys_select_intr(). This is a mistake (I believe) as it allows
a signal to early terminate the connection attempts - whereas
sys_select_intr() will ignore signals until we get back to
the main processing loop where they'll be handled correctly.
This change means winbindd_cm will not early terminate if it
gets a message whilst trying to connect to DC's.
Gunther, Volker and Jerry please review (but I think this
is correct).

fsp pointers. Ensure we cope with this to pass Samba4
DENY tests (we used to pass these, there must have been
a regression with newer code). We now pass them.
